General

It provides better productivity as it achieves the maximum speed of 2,700sti/min and is quipped with the high speed trimmer. With our original horizontal forced feed mechanism, the button carrier sets a button in position so that the operation is simplified. Furthermore, operator fatigue is reduced since what operator needs to do is only setting material and pressing a pedal.
